公路作为一种交通运输方式,对全世界的社会和经济的发展起着至关重要的作用,卢旺达的公路建设项目面临各种各样的风险因素,造成延误,这些风险因素主要包括:项目建设范围变化、通行权限制、资金不足、项目管理不善、天气条件恶劣、施工和财务风险。项目管理的关键问题是通过分析阻碍项目成功交付的影响因素以减小项目交付风险和不确定性来实现项目按时交付的目标。本文主要深入分析了导致卢旺达公路工程建设项目延误的主要风险因素、对工程项目的影响并提出了相应的缓解措施。采用相对重要性指数(RII)对调查对象的数据进行分析和排序。通过研究发现,资金不足、天气条件恶劣、沟通不畅、范围变更、规格不准确、不完整、缺乏协调、地质条件不可预料、错误返工、承包商财务困难、所需设备短缺是导致项目延迟交付的主要原因;成本超支、时间超支,经济合同纠纷与索赔、项目完全终止及社会负面影响是工程延误对项目的最显著影响;增加沟通和透明度,建立一个协作和综合团队,增加人力和/或设备,密切监督,使用BIM(建筑信息建模)和项目的实际进度安排等措施被列为减小延误风险的主要措施。本文主要通过对卢旺达某延误了3个月的公路工程项目进行案例分析,发现天气条件恶劣和现金流不畅等财务问题是造成项目延误的主要风险因素。本研究认为,风险管理是参与项目实施各方的首要目标,并且必须制定和实施适当的风险控制计划。因此,本文建议在项目执行之前,从项目开始的早期阶段就识别、评估可能导致该项目延误的风险因素从而减小该项目的延误风险并防止负面的社会影响。

Predictive Mathematical and Statistical Modeling of the Dynamic Poverty Problem in Burundi: Case of an Innovative Economic Optimization System

Open Journal of Optimization 2021年第4期10卷 101-125页

作者： Fulgence Nahayo Ancille Bagorizamba Marc bigirimana Irene Irakoze ISTA/University of Burundi Bujumbura Burundi

The mathematical and statistical modeling of the problem of poverty is a major challenge given Burundi’s economic development. Innovative economic optimization systems are widely needed to face the problem of the dynamic of the poverty in Burundi. The Burundian economy shows an inflation rate of -1.5% in 2018 for the Gross Domestic Product growth real rate of 2.8% in 2016. In this research, the aim is to find a model that contributes to solving the problem of poverty in Burundi. The results of this research fill the knowledge gap in the modeling and optimization of the Burundian economic system. The aim of this model is to solve an optimization problem combining the variables of production, consumption, budget, human resources and available raw materials. Scientific modeling and optimal solving of the poverty problem show the tools for measuring poverty rate and determining various countries’ poverty levels when considering advanced knowledge. In addition, investigating the aspects of poverty will properly orient development aid to developing countries and thus, achieve their objectives of growth and the fight against poverty. This paper provides a new and innovative framework for global scientific research regarding the multiple facets of this problem. An estimate of the poverty rate allows good progress with the theory and optimization methods in measuring the poverty rate and achieving sustainable development goals. By comparing the annual food production and the required annual consumption, there is an imbalance between different types of food. Proteins, minerals and vitamins produced in Burundi are sufficient when considering their consumption as required by the entire Burundian population. This positive contribution for the latter comes from the fact that some cows, goats, fishes, ···, slaughtered in Burundi come from neighboring countries. Real production remains in deficit. The lipids, acids, calcium, fibers and carbohydrates produced in Burundi are insuffic

Introduction: Africa was noted as a challenging place for allied health care professions including occupational therapy. Those challenges include promotion of occupational therapy and educational program. The University of Rwanda started the occupational therapy training program in 2014 with support of different stakeholders such as Humanity & Inclusion (HI), Rwanda. Aim: This study aimed to explore the contribution of different stakeholders in the development of occupational therapy programs and impact on the profession in Rwanda. Methods: A survey and mixed method of qualitative and quantitative approach was used. Client satisfaction questionnaire, semi-structured self-generated questionnaire were administered to the participants. Results: The majority of occupational therapists were between 20 and 30 years old and only half of the entire population were employed. Majority of the involved Universities excellently achieved their responsibilities. However, few of them reported to have achieved only 50% of their responsibilities. Other contributors like lecturers reported to have excellently achieved their duties while others reported to have achieved only 50%. Non-Governmental Organizations reported to contribute to enough level however there were some organizations contributed to the lowest level below 50%. The client receiving the Occupational Therapy services showed that they are very satisfied at the level of 73.5%, satisfied at 59% and not all satisfied at 20%. Conclusion: This study concluded that there is need for various stakeholders’ contributions, and a need for further study to explore the impact of occupational therapy profession in rehabilitation healthcare system of Rwanda.
